This is asking you to understand the concept of osmoregulation.
00:08
Okay.
00:11
So i'm going to help us understand what, you know, basics of osmeregulation.
00:15
They're just the basics, all right? because we are told to define osmoregulation and then give its function.
00:26
Okay, you know, what role does it play in different systems for us? sense okay now osmo regulation is what we call active regulation acting active regulation of osmotic pressure okay very many organisms regulate the osmotic pressure of body fluid right when we talk of osmotic pressure we normally mean body fluids right and basically, this is what happens when some parts, let me say, cellular parts known as small receptors come in, right? and this means that a collection of this mechanism will definitely maintain a concept of homeostasis, the constant internal environment of a given organisms for maximum functionality of this organism, right? for instance look at the paramecium.
01:43
Paramecium is a fresh water organism, microorganism, that strives to balance the concentration of water molecules inside and also the cell.
01:54
That's why it acquires a very clever way, or let me say organelle known as a contractile vertical.
02:03
Okay.
02:05
What happens is that this contracted vacuum pumps out excess water.
02:09
You know, to prevent these organisms cells bursting, you see, this is what you call osmone regulation.
02:15
Okay.
02:16
It takes care of the balance of body fluids in this organism, all right? okay...
